signalert

Signalert is a framework for real-time monitoring and alerting of signage systems used in transportation, public safety, and digital advertising. It defines how status and health data from roadside signs, dynamic displays, and related equipment are collected, processed, and distributed as alerts to operators, maintenance crews, and end users.

Core components typically include edge devices attached to signs, a central processing platform, and multiple notification channels. Edge devices report metrics such as power state, illumination, communication health, content validity, and tamper or vandalism indicators. The central platform normalizes events, applies an alert taxonomy, and routes notifications via APIs, text messages, emails, push notices, or integration with incident-management systems.

Signalert emphasizes interoperability through open data models and protocols to connect with traffic management centers, asset management systems, and civic applications. Features commonly include event filtering, escalation policies, audit logs, access control, and secure data transmission. Deployment models often blend on-premises gateways with cloud-based analytics for scalability and resilience.

Applications span urban signage networks, highway dynamic message signs, school-zone boards, and public information displays. Security and privacy considerations focus on authentication, encryption, tamper resistance, and minimization of sensitive data exposure.

Origin and status: Signalert emerged as a general naming concept in municipal signage projects, with various vendors and open-source efforts adopting similar capabilities. There is no single universal standard, but the term is used to describe a family of compatible alerting workflows.
